Random thoughts: 

-when reinstalling BCM 3.7 (Windows NT4.0 version,) or changing out the hard-drive: make sure that you plug the hard drive into the IDE 0 slot.  It will NOT boot from IDE 1.
-periodically power the system down, disconnect power cable, and pull the trays out one by one.  Blow out any fluff or dust bunny colonies and reseat all your connectors.


BCM400 3.7 Software

-Nortel IP Softphone 2050
    In my personal opinion, Version 2.00.0239 is far better than Version 1.40.0363 that was included with BCM3.7
    And, it works with 64-bit Windows 10...

BCM400 Hardware

Media Services Card 


The Media Services Card (MSC) connects to the BCM400 Base Function Tray (BFT) through the PCI slot on the SH815 motherboard. It provides digital signal processing, buses for Media Bay Modules and contains system programming on multiple FLASH/RAM chips. System memory is maintained by a large supercapacitor. The MSC carries the DS2401 silicon serial number chip (U18) that provides the System ID. All feature licensing is driven by the System ID. In diagnosing hardware failures, be sure to try the MSC on a new BFT in order to preserve your licensed features.
